nonconvulsive epilepsy

Hi everyone I was sorting someof my old medical documents yesterday, and I came across a sheet from my Rhumies office, the one where they mark diagnosis and order labs, and how much you owe. Any how on the diagnosis part in addition to SLE she had another box checked "nonconvulsive epilepsy". I don't know why I didn't notice it before, but I did now . Any how, I tried looking up nonconvulsive epilepsy and seeing how itfits in with SLE. The only thing I can come up with so far is that both conditions can cause high IGG levels. Are there any others here who have this DX? Do any of you know anything about "nonconvulsive epilepsy" ? Any info is appreciated, Thanks
